Delegate display on row selection in QTableView

neel2818

Hi,

I have implemented the custom delegate in QTableView. In One column i have set the ComBox as delegate in QTableView.
Problem is when i select the row of QTableView then ComboBox is not getting displayed. Combobox is only ge displayed when i clicked on second column where i have set the delegate.
@ QComboDelegate(QAbstractItemView* view)
{
this->view = view;
}

    virtual QWidget* createEditor( QWidget* parent, const QStyleOptionViewItem& option, const QModelIndex& index ) const
    {
        Q_UNUSED(index);
        Q_UNUSED(option);

        QComboBox* editor = new QComboBox( parent );

        editor->installEventFilter( const_cast<QComboDelegate*>(this) );
        editor->setAutoFillBackground(true);
        QObject::connect( editor, SIGNAL(currentIndexChanged(int)), view, SLOT(sensorModeChanged(int)));

        return editor;
    }


    virtual void setEditorData( QWidget* editor, const QModelIndex& index ) const
    {
        QComboBox* combo = static_cast<QComboBox*>( editor );

        combo->addItems( comboList() );
        int idx = QComboDelegate::comboList().indexOf( index.data( Qt::DisplayRole ).toString() );
        combo->setCurrentIndex( idx );
    }

    virtual void setModelData( QWidget * editor, QAbstractItemModel* model, const QModelIndex& index ) const
    {
        QComboBox* combo = static_cast<QComboBox*>( editor );

        model->setData( index, combo->currentText() );
    }

    virtual void updateEditorGeometry(QWidget *editor,
                                      const QStyleOptionViewItem& option, const QModelIndex& index ) const
    {
        Q_UNUSED(index);
        int hCell = option.rect.height();
        int hEditor = editor->sizeHint().height();
        int h = qMax( hCell, hEditor );
        QSize size = option.rect.size();

        size.setHeight( h );
        editor->setGeometry( QRect( option.rect.topLeft() - QPoint(0, (h - hCell) / 2), size ) );
    }

    /**
     * handle the events anf filter the required events
     */
    virtual bool eventFilter( QObject* obj, QEvent* event )
    {
        if ( event->type() == QEvent::KeyRelease && static_cast<QKeyEvent*>(event)->key() == Qt::Key_Return ) {
            emit commitData( static_cast<QWidget*>(obj) );
            emit closeEditor( static_cast<QWidget*>(obj), EditNextItem );
        }

        return false;
    }@

Can you please help me how to do when i select the row then delegate should be displayed ?

Thanks,
Neel
